Omphalis
A workspace for understanding
About Omphalis
Saved something because it mattered, and now you can't find the passage or remember why? Omphalis is a workspace for understanding. Bring articles, PDFs, papers, podcasts, videos and YouTube links into one place. When a section gets hard, an explanation opens beside the passage, so you stay in the piece instead of switching tools. Ask one question across several sources, and the answer cites the passages it used. Your highlights, questions and notes stay with the source, so you can come back later and build on what you've learned. Use it on the web, iPhone and Android, or with the Chrome and Firefox extensions. There's a free plan. Paid plans start at $9 a month, with a 30-day trial, no card required. The trial includes 200 voice minutes, 200 PDF pages and 15 answers a day.
